Gas stoves installed in rental properties will develop faults and malfunctions as years of use accumulate. Even if tenants use them carefully, replacement is necessary when they reach the end of their lifespan. This article provides a detailed explanation of the useful life of gas stoves, how to handle breakdowns, and who bears the costs in rental properties.
How Long Is the Useful Life of a Gas Stove?
The statutory useful life of gas stoves is approximately 6 years. However, this is the depreciation period for tax purposes and differs from the actual lifespan.
Actual Lifespan by Type
| Type | Statutory Useful Life | Actual Lifespan Estimate |
|---|---|---|
| Freestanding (table-top gas cooker) | 6 years | Approx. 5–7 years |
| Built-in type | 6 years | Approx. 7–10 years |
Even after the statutory useful life, if there are no problems, continued use is fine. However, the risk of breakdown increases proportionally with age, making regular inspection important.
Check the Lifespan of Batteries and Gas Hoses
Not just the main unit—related parts also have lifespans.
- Batteries: Need replacement every 6 months to 1 year
- Gas hose: Approximately 6–7 years for city gas, approximately 3 years for propane gas
What seems like a stove malfunction may actually be caused by dead batteries or deterioration of the hose.
What Symptoms Appear When the Useful Life Is Approaching?
As a gas stove approaches the end of its life, the following symptoms appear. Early detection leads to safe use.
Difficulty Igniting or Goes Out on Its Own
The most common symptom. If not resolved by battery replacement, the unit may be at the end of its life. Forcing ignition in this state is dangerous as it risks incomplete combustion.
Flame Color Turns Orange or Green
A normal flame is blue. Orange or green color is a sign of incomplete combustion. If you smell gas, there is a risk of carbon monoxide poisoning—immediately ventilate and contact the gas company.
Strange Noises
If strange noises continue after cleaning and battery replacement, the unit is likely at the end of its life. Have it inspected promptly.
Gas Smell
Gas buildup from incomplete combustion can cause carbon monoxide poisoning. If you smell something unusual, immediately stop use and consult a professional.
What Should You Do First When a Gas Stove Malfunctions?
Before replacing, try the following remedies. Many cases can be resolved with simple fixes.
- Battery replacement: The most basic remedy. Be careful with older models that lack a low-battery indicator light
- Cleaning the burner cap: Dirt and moisture can cause uneven gas distribution leading to ignition failure
- Checking burner cap placement: If it's raised, gas won't flow—lightly rotate to check for misalignment
- Cleaning the grill: Food scraps and grease deposits cause odors and smoke
- Checking the safety device (Si function): Present in stoves since 2008. Dirt on the sensor section often causes false operation
- Checking the gas valve: It may have been closed after a regular gas company inspection
- Checking hose condition: Check for deterioration or kinks. For peace of mind, have replacements handled by a professional
- Checking child lock: The lock may be engaged without your knowledge
- Checking accessories: Non-genuine items may not be recognized
Who Bears the Cost When a Gas Stove Breaks Down in a Rental Property?
The basis for determining who bears the cost differs depending on who installed the gas stove and the cause of the breakdown.
| Case | Who Bears the Cost |
|---|---|
| Installed built-in type (age-related deterioration) | Landlord (Owner) |
| Installed type (tenant's intentional damage or negligence) | Tenant |
| Freestanding type installed by landlord | Landlord (Owner) |
| Items left by previous tenant | Tenant |
Installed built-in stoves are considered "equipment," and replacement costs due to age-related deterioration are in principle borne by the owner. On the other hand, freestanding stoves left by previous tenants are treated as "abandoned items," and tenants bear the repair and replacement costs.
If there are abandoned items, it is important to ensure they are clearly recorded in the rental contract and important explanation documents.

When replacing, choose products that contribute to improved tenant satisfaction.

How Should You Choose a Gas Stove Replacement Contractor?
Here are 3 points to avoid mistakes when choosing a contractor.
- Prompt response: Check speed of response to inquiries and thoroughness of explanations
- Free estimate service: Request estimates from at least 2–3 companies to determine if the price is appropriate
- Comparison of service content: Also check 24-hour service, same-day service, after-sales support, and disposal of old stove
How to Efficiently Manage Equipment Replacement Costs?
Regular management is important to avoid panic when equipment suddenly breaks down. Here are points for achieving stress-free rental management.
- Understand useful life and replace in advance: Using 10 years as a guideline, avoid emergency response while tenants are in residence
- Record existing equipment: Record model numbers and condition with photos for the ability to request estimates directly from the internet
How to Respond If Asked for Rent Reduction Due to Gas Stove Breakdown?
If repair/replacement is done promptly, there is no need to agree to a rent reduction. However, under Civil Code Article 611, there is a possibility of rent reduction claims for the period when equipment was unusable.
The reduction ratio when gas is unavailable is 10% of the monthly amount, with a grace period of 3 days. The actual reduction amount is approximately a few hundred to a few thousand yen.
Since the 2020 Civil Code reform may increase reduction claims, clearly state conditions such as "report breakdowns within X days" and "maximum reduction is X yen" in the contract.
